Step 5 Temperatures
Temperature categories are loosely based of the Thewartha system
Monthly mean temperatures of each categories
Dark magenta - Severely hot: over 35°C
Red – Very hot: 28 to 35°C
Dark orange – Hot: 22 to 28°C
Orange – Warm: 18 to 22°C
Peach – Mild: 10 to 18°C
Yellow – Cool: 0 to 10°C
Green – Cold -10 to 0°C
Turquoise – Very cold -25 to -10°C
Blue – Severely cold: -38 to -25°C
Violet – Deadly cold: under -38°C
5.1 Zone of temperature (also called influence):
We separate the world into several zones to make the distribution of temperature according to the influence each region is subject to.
The different zones are:Hot current (red) : areas affected by winds blowing from a hot current. Hot current have no impact in summer since the land is hotter than the water and it’s considered normal instead.
Also, they have no impact between the tropics either.
Mild current (green): Includes
Mid latitude currents that have cooled, as a transition from hot to cold.
Where cold and hot currents meet. Usually around 40-45 degrees or elsewhere like South Africa.
Cold current (blue): These are the coldest currents. They make the land colder compared to other locations at the same latitude.
Normal: the default temperature at a given latitude.
Continental: Occur on large landmasses, under high pressure systems in winter but under low pressure systems in summer.
Stronger in the center or the eastern side of the continents if the winds have been blowing overland for a long time.
Areas trapped in a sea of ice like the Canadian and Russian Arctic are also considered continental: ice limits the heat exchange and reflect light back to space.
Continental plus: Is an extreme version of the above. It requires larger landmasses. The only known case is Central Asia in summer.
